A constant pressure air thermometer gave a reading of 47.5 units of volume when immersed in ice-cold water, and 67 units in a boiling liquid. The boiling point of the liquid, is

Options

  1. A125^ C
  2. B100^ C
  3. C135^ C
  4. D112^ C .

Correct answer

D. 112^ C .

Step-by-step solution

A constant pressure air-thermometer is based on the law V₁ T₁ = V₂ T₂ T₂ V₁ = V₂ V₁ Here it is given that V₁=47.5 aligned & V₂=67 & T₁=0^ C =273 ~K aligned aligned T₂=273 67 47.5 & =385.07 ~K & =112^ C aligned
